If you are seriously considering selling, you would be best to look at going back to stock.
Your jeep is actually worth more stock.
Start with finding a stock runi that wants your gears. Have him pay about half of what it would cost to do gears and swap diffs.
You get 1000 or so dollars, and he gets gears for half price.
Put some stock rubber and suspension under it, and save all your stuff for your build, or sell it for build funds.
Sell the rubi and get into a 97-02 tj.
With the diff swap, price difference, and money from parts, you should have a minimum of 10k to go towards a 38's build.
Or you can sell you buit diffs for around 4k, tires an suspension for 1500 or so and start with 5500 towards the build.
Up to you.
It would be nice to be out of the 6 speed, mercedes steering box, late model cam sensor, and emission heavy camshaft.
The 97-99 has the most power due to a less restrictive cam profile.
Oh ya, and pre 03 models have upgradeable alternators via various junk yard swaps. The late models dont because the mounting is all changed.
Hopefully that helps.
